 ?> If you're using an older browser that doesn't support the `formdata` event, a lightweight polyfill will be automatically applied to ensure forms submit as expected.
 
+## A Note About Event Capturing
+
+Shoelace uses event listeners to intercept the form's `formdata` and `submit` events. This allows it to inject form data and activate client-side validation as necessary. The [`capture`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener#parameters) option is used to ensure events are intercepted as early as possible. This means if you're using `addEventListener()` without the `capture` option, you have nothing to worry about.
+
+However, if you're using the `capture` option, you must attach the listener _after_ Shoelace form controls are connected to the DOM. Otherwise, your logic will run before Shoelace has a chance to inject form data and validate form controls.
+
 ## Form Serialization
 
 Serialization is just a fancy word for collecting form data. If you're relying on standard form submissions, e.g. `<form action="...">`, you can probably skip this section. However, most modern apps use the [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) or a library such as [axios](https://github.com/axios/axios) to submit forms using JavaScript.
